Discussion

Hypothesis-generating for non-contact mapping-guided ablation in PVC-related LV impairment; prospective trials needed before practice change.

Does radiofrequency ablation improve left ventricular impairment in patients with frequent ventricular bigeminy?

Population

1 patient with frequent ventricular bigeminy resulting in left ventricular impairment (dilated cardiomyopathy)

Intervention

Radiofrequency ablation using non-contact mapping

Outcome

Resolution of left ventricular impairmentsurrogate

Radiofrequency ablation is an effective treatment strategy for suppressing frequent PVCs and reversing associated left ventricular dysfunction.

Shanmugam et al. (2006) studied this question.
